摘　　要：针对秸秆燃料乙醇废水污染物含量高、粘度大、酸性强等特点,采用上流式厌氧污泥床(UASB)-间歇式循环延时曝气活性污泥法(ICEAS)-Fenton组合工艺进行处理研究;结合GC-MS分析,探讨了该组合工艺处理过程中主要阶段的运行。结果表明,最终出水COD去除率约为98.24%、NH_4^+-N去除率约为95.24%,均能达到CJ 343-2010二级排放标准。可为含氮量高的工业废水或难降解的高含量废水提供理论支持与数据参考。The UASB-ICEAS-Fenton assembled process was applied to treat the straw fermented fuel ethanol wastewater in viewing of its characteristics like high concent, high viscosity and strong acid etc. The GC-MS based analysis was conducted for the major operational part of the assembled process. The results showed that COD and NH4^-N removal efficiency of 98.24% and 95.24% can be achieved in the effluent, all of which met well with the secondary discharge standard of CJ 343 --2010. This study can be used as a theoretical support and reference for other industrial wastewater with high concent of nitrogen and refractory compounds.
